Henoch-Schönlein Purpura (HSP) in Children
What is Henoch-Schönlein purpura in children?
Henoch-Schönlein purpura (HSP) is a condition that involves swelling (inflammation) of small blood vessels. The swollen blood vessels leak into the skin, joints, intestines, and kidneys. HSP is seen most often in children between ages 2 and 6. It occurs more often in boys. The disease can happen in siblings of the same family. Most children with HSP recover fully. But some children may have kidney problems.
What causes Henoch-Schönlein purpura in a child?
HSP is an autoimmune disorder. This is when the body’s immune system attacks the body’s own cells and organs. With HSP, this immune response may be caused by an upper respiratory tract infection. Other immune triggers may include an allergic reaction, medicine, injury, or being out in cold weather.
What are the symptoms of Henoch-Schönlein purpura in a child?
Each child’s symptoms can vary. Common symptoms include:
A rash caused by blood leaking into the skin
Blood leaking into mucous membranes, internal organs, and other tissues
Joint pain and swelling (arthritis)
Belly (abdominal) pain
Bleeding in the digestive tract, which includes the mouth, esophagus, stomach, and intestines
Swelling just below the skin
A brain disorder
Inflammation of the testicles
These symptoms can seem like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
How is Henoch-Schönlein purpura diagnosed in a child?
Your child’s healthcare provider will ask about your child’s health history and do a physical exam. Diagnosis is based on symptoms such as:
Your child may also need tests, such as:
Biopsy. Small tissue samples may be taken. They may be taken from the skin or the kidney. They are looked at with a microscope. This may only be needed if the diagnosis is unclear.
Blood and urine tests. Your child's urine will be checked for blood and protein. A blood test can check kidney function.
Ultrasound. This imaging test uses sound waves and a computer to make pictures of blood vessels, tissues, and organs. It may be used to look at the digestive tract for signs of the disease.
How is Henoch-Schönlein purpura treated in a child?
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.
Treatments for HSP may include:
Making sure your child drinks enough fluids
Making sure your child eats a healthy diet
Taking medicines such as acetaminophen to help ease pain
Taking glucocorticoids to control inflammation
Taking blood pressure medicine to lower blood pressure if needed
Natural supplements such as fish oil and antioxidants may help
Talk with your child’s healthcare provider about the risks, benefits, and possible side effects of all medicines.
What are the complications of Henoch-Schönlein purpura in a child?
Most children with HSP recover fully. But some children may have kidney damage. In rare cases, a child may have kidney failure. Women who have had HSP as a child have a higher risk for pregnancy-induced hypertension (pre-eclampsia).
When should I call my child’s healthcare provider?
Tell the healthcare provider if your child’s symptoms get worse or there are new symptoms.

Tips to help you get the most from a visit to your child’s healthcare provider:
Know the reason for the visit and what you want to happen.
Before your visit, write down questions you want answered.
At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.
Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.
Ask if your child’s condition can be treated in other ways.
Know why a test or procedure is recommended and what the results could mean.
Know what to expect if your child does not take the medicine or have the test or procedure.
If your child has a follow-up appointment, write down the date, time, and purpose for that visit.
